Y., A CORPORATION or nnLAwAnE MACHINE FOR FORMING ToILETYsnA'r covnns Original application filed December 11, 1929, Serial No. 413,186. Divided and this application filed December 17, 1930.

The present invention relates to machines for making and vending or dispensing toilet seat covers. v

The present invention contemplates an improved machine for this purpose wherein all the parts are designed and arranged for easy. assembly in a small cabinet, adapted to hold a supply of tissue in the form of a roll, and to form and dispense the toilet seat covers ready for use. The seat cover is formed out of the web by cooperative male and female rolls bearing a predetermined design. These rolls arepreferably arranged for tearing the paper along the desired lines instead of cutting it by a sharp knife. 7

An object of he present invention is to provide a machineof this type wherein the male cutting or tearing roller is skeletonized and the cutting or tearing knives are formed out of sheet metal parts wrapped about the cylinder.

The present applicationis a division of my co-pending application, Ser. No. 413,186, filed Dec. 11, 1929, forMachines for making and vending or dispensing toilet-seat covers.

The accompanying drawings. show, for purposes of illustrating the present invene tion, one of themany embodiments in which it may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In these drawings:

The present machine is shown'as being embodied in a sheet metal cabinet adapted to be mounted on the wall or other convenient formed in the support. The cabinet'is open at the front controlled lock indicated at 20.

Serial No. 502,905.

and a two-part bottom wall 13, 14. The front edge of'the lower bottom wall part 13 is bent upwardly and rearwardly, as indicated at 15, while the rear edge of the front part l4 of the bottom wall is bent upwardly as indicatedat 16. The parts 15 and 16 form a delivery. chute for the formed seat cover.

The front cover of thecabinet is shown at 17. It is hinged as indicatedat 18 and at the top extends rearwardly as indicated at 19 to close the top of the cabinet. It is adapted to be locked in this position by a key The cover also has side walls 21 and 22 extending rear.- wardly and adapted to overlie the side Walls 11 and 12 of the stationary part of the cabinet.

As here shown, the seat-forming mechanism is carried between two plates 23 and 24. These plates are secured to v the side walls 11 and 12 of thecabinet byscrews, indicated at 25, these screws passing through holesin the side wallsv of. the cabinet, and being threaded into tapped holes in the cast frame plates 23 and 24. The male .roller 26 for the seat cover forming mechanism is shown more in detail in Fig. 3. It may be carried on a shaft 27 mounted in bearing holes 28 in the frame plates 23 and 24 This shaft carries three discs28, 29 and 30 and these discs carry the male cutting or tearing knives for forming the seatjcover. p

The machine herein shown is arranged to forma seat cover of the shape shown in Fig. 5. The front end of the seat cover is the first to emerge fromthe machine and is V- shaped as indicated at a, a. The rear end of the seatlcover is also V-shaped as'indn cated at Z), I). An oval flap is cut centrally in the cover, the flap having the shape indicated ate. p

. The male roll is provided with two dull knives indicated at 31 and 32. The knife 31 is in the form of a strip of sheetmetal, as appears more clearly in Fig. 3, and is secured to the threey discs 28, 29 and 30 by screws indicated at 33. p This knife is provided with spiral edges 34 and 35 arranged normal to the surface'of thecylinder, these edges 34 and being formed by bending the sheet metal outwardly. They are adapted to form the V-shaped ends a, a, b, b of a seat cover. The knives 33 and 34, as here shown, are separated at 36, this narrow gap being provided so that the seat cover formed is not completely severed from the material remaining in the machine. The flap forming knife 32 is also made of sheet metal. It is provided with continuously curving edges 37 arranged normal to the surface of the cylinder, and of such shape as to cut the flap c. The cutter 32 is secured to .the disc 29' by screws 38.

The female roll is indicated at 40. It is one-half the diameter of the male roll and is provided with a curved slot 42' adapted to receive the cutting edges 37 of the flap forming knife,- and with other helical slots 43 adapted to receive the end forming knives 34 and 35. This female rollmay be made out of any suitable. material, such for ex ample as a molded material. It is mounted on a length of tubing 45 which carries'spur gears 46 and 47. r

' Thegears 46 and 47 are-mounted on a shaft indicated at 48, this shaft being carried in the frame plates 23 and 24. The gear 46 onthe righthand end of the-roll 40 meshes-with a gear 48 carried on the shaft-27 ofthe male roller. This gear is twice'the-size of the gear 46-so as to maintain a tWo-to-one relation between the male and female rolls.

' AguiderQll-S'O is carried inelongated bearing openings 51 at the front of the frame plates 23 and 24'. This guide roll" is preferably provided with adouble spiral rubber paperspreading device52, and'is held against the surface of the female roller seas topress the paper against thefemale roller and spread the paper away from thecenter to prevent the formation of longitudinal creases.

'A pressure roll 53 is mounted to the rear of the female roller, being preferably carried in elongated slots 54in'the plates 23 and 24, anddriven'by a'gear 55 meshing with the gear 47 The rolls 50 and 53-are held against the surface of the female roller by coiled springs 58 carried between the-gearsand end plates. The roll 50 grips the entire width of the-seat cover after severing. and holds it while it hangs from the machine and until it is torn away. The shaft 48' is driven by a-crank C, and forward turning ofthe parts is insured by apawl 59.

The cover 17 is provided with angle members 61 adapted to support the ends of a shaft 63. "This shaft carries a roll of tissue 64 I from which the toilet seat covers are to be made. In insertingthe paper into the machine, the cover is lowered about the hinge 18 and allowed to hang down, the roll of a paper placed in position with the shaft 63 underneath the flange 61. The end of the paper is then passed underneath the guide roll 50 and between the male and female rollers, these rollers being actuated by the crank C. After the paper passes between the rolls 26 and 40, the paper is guided downwardly by the pressure roll 53 and passes out through the chute as will be clear from Figs. 4 and 5. 'The cover 17 may then be raised up to close the cabinet. This carries the roll up to the position indicated in full lines in Figs. 4 and 5 without disturbing the paper which has been previously fed through between the rolls.

It is contemplated that the machine will be provided with suitable mechanism for automatically stopping it at the end of a seat forming cycle and with a release device, either manually controlled or coin controlled, so that it may be again started into opera tion for dispensing another seat cover.

It is obvious that the invention may be embodied in many forms and constructions, and I Wish it to be understood that the particular form shown is but one of the many forms. Various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.

I claim:

1. In a machine for forming toilet seat covers out of a web of paper, a male roll comprising discs mounted on a shaft, and an end forming knife comprising a strip of sheet metal bent to form a fragment of a cylinder and secured to the discs, the strip having a spiral shaped edge normal to the surface of the cylinder.
